vPaamad oa. 22,4 1929 oFFIce LUCIUS V. HAMILTON, F INDIANAPOLIS, INDIANA WEATHER STRIP ApplicationA led December 26, 1928. Serial No. 328,341.

z This invention relates generally to means for preventing the passage of air currents through the clearance spaces ofwindows, doors and the like, and specifically to a weather-strip and guide structure having for its primary objects the effective stopping of the openings around the edges of closure mem bers by a simple structure quicklfy and cheaply installed to give a plurality o lines of closure in yielding contact.

The invention is described in the one particular form as shown in the accompanying drawing, in which Fig. 1 is a fragmentary elevation of a sash and frame including my invention applied thereto; A

Fig. 2, an enlarged transverse horizontal section on the line 2-2 in Fig. 1; and

Fig. 3, a side elevation in perspective of a. short section o the sash strip.

Like characters of reference indicate like v parts throughout the several views in the drawing. v l

My invention is adapted to be applied readily to the sash as now customarily employed. In each of the vertical edges of the sash 10, I cut a slot or rabbet 11, and in this slot 11, I position and secure by the nails 12, the strip Y generally designated by the numeral 13.

The strip 13 is preferably made from bronze'spring stock and is rolled to have a sharp V base 14, and from the end of each leg of the V is extended a short straight section 15 having an arm 16 bent inwardly therefrom and terminating in a short leg 17 bent back outwardly.

The space between the sections 15 is such that the strip 13 must be pressed into the rab bet 11 with the section 15 compressively en t@ ga-ging the side of the rabbet and the point of the V base contacting the bottom of the rabbet. Only a few nails -12 are required to retain the strip 13 in the rabbet and the rabbet 11 is cut suliciently deep to carry the strip en- @5 tirely therewithin, the lets 17 be1n"g just below the surfadeo the sash edge.

A sash guide strip generally designated by the numeral 18 is formed preferably of zinc to have anelongated V section 19 projected outwardly from the plane of the two oppositely extended legs 20 and 21. The leg 21 is further formed with a bead 22 throughout its length. The V section 19 is entered between the arms 16 of the sash strip 13 to be compressively engaged therebetween and nails 23 are driven through the legs 20 and 21 to secure the guide strip in place on the frame 24 so that the sash 10 may be moved up and down in a guided relation alone' the guide 18 with the arms 16 compressively contacting the guide.-

The sash 10 bears against the bead 22 which serves as a line contact to aid in the ree travel pif te sash 10 in holding it away from the nail It is tobe noted that the sliding oint between the sash 10 and framev 24; is e ectively sealed. Supposing the sash 1() to be shifted edgewise from the head 22 suiiciently to let a current of air pass thereb the air cannot pass between the strip 13 an the sash for the reason that the flat sections 15 are compressively held in contact with the side walls of the rabbet to form two scalinor lines in addition to the line of contacts by tlie V base of the strip in the bottom of the rabbet. Should the sash warp laterally as it generally does in winter, the legs 20 and 2l will give sufficiently to maintain an air seal and yet permit -the parts to slide over one another.

Neither can the air pass between the frame strip 18 and the sash strip 13 since'the arms 16 compressively engage 1n two lines of contact on the V section of the strip 18. The bead 22 may be rolled in the le 21 to :further serve as a resilient means where y pressure of the sash ed e thereagainst will tend to flatten the bead 2 to effect a further seal between the frame and sash.

,While I have here described and shown my invention in the best form now known to me, I do not desire to be limited to that precise form, norany more than may be required by the following claim, since structural deviations may be made without departing from the s irit of the invention.

I c aim: n

In combination with a frame and a sash, said sash having a rabbet cut in its edge, a

4frame guide strip, and a sash strip, said sash strip having a V base secured by its apex centrally along the bottom of the rabbet with the outer ends of the base compressively contacting the side walls of the rabbet, and having an arm extending from 'each outer end of the base to yieldingly contact on a portion of said frame strip received therebetween, said frame strip hailing a leg laterally extended on the frame, and a bead in said frame strip leg over which said sash may slide.

In testimon whereof I aflix my signature.
